Planning for an IQ Microinverter System

Consider placing the enclosure in a location that is accessible by service personnel without requiring
indoor access.
The IQ Envoy ships with a production CT. This must be installed in the solar subpanel to meter the
microinverter branch circuit conductors.
Metering CT requirements:
o Use a protected route in conduit for the production CT wires from the solar subpanel to the
IQ Envoy. If you also use consumption CTs, use protected route in conduit from the main
service panel or main service feeder access point to the IQ Envoy
o Pass Line 1 only of each microinverter branch circuit through the production CT. The
microinverter branch circuit Line 1 conductor must be electrically on the same busbar as the
Line 1 conductor feeding the IQ Envoy.
o You may run multiple Line 1 conductors for each microinverter branch circuit through the
production CT. Remember to wire the microinverter branch circuit Line 1 conductors with the
arrow on the production CT pointing from the microinverters to the interconnection point.
o Do not extend the production CT sense wires.
Consumption CT wires can be extended if needed. Follow recommendations in IQ Envoy Installation and
Operation Manual.
